Loading a 2D netcdf CF dataset in 2.4.0.RC0

I am trying to load a 2D netcdf CF dataset, containing rainfall amounts (mm/hr), in VAPOR 2.4.0.RC0.
My problem is that it loads, but with following user coord extents (X,Y,Z) and grid extents (X,Y,Z) (seen in the 2D section of VAPOR):
user coord extents (X,Y,Z):
Min: 0 0
Max : 1 0.608696

grid extents (X,Y,Z):
0 0 0
344 209 0

These are not the geographical LAT-LON coordinates (X,Y,Z) that are in the CF file, and also not the proper grid extent 345x210.

Can anybody help me ? I can provide the netcdf CF file if needed.
Here its header:
ncdump -h test.nc
netcdf test {
dimensions:
west_east = 345 ;
south_north = 210 ;
time = UNLIMITED ; // (73 currently)
variables:
double lon(west_east) ;
lon:standard_name = "longitude" ;
lon:long_name = "longitude" ;
lon:units = "degrees_east" ;
lon:axis = "X" ;
double lat(south_north) ;
lat:standard_name = "latitude" ;
lat:long_name = "latitude" ;
lat:units = "degrees_north" ;
lat:axis = "Y" ;
double time(time) ;
time:standard_name = "time" ;
time:units = "hours since 1998-09-12 00:00:00" ;
time:calendar = "standard" ;
float RAIN(time, south_north, west_east) ;
RAIN:units = "mm hr-1" ;
RAIN:_FillValue = -9.e+33f ;
RAIN:coordinates = "lon lat" ;
